I've got a family BBQ tomorrow, about 10 of us. Brother's (29) girlfriend (27) is quite difficult and now makes me dread all family gatherings. She doesn't engage in any conversation, mostly sits in the corner and spends the entire time looking really bored, yawning, and on her phone. We have all been really friendly, (we're not a rowdy or rough bunch or anything) and encourage her to join conversations, but it's like she just doesn't want to talk to us, it's so odd. She comes across as snooty to be honest. Because I'm the only younger adult woman in the family (I'm 32) the responsibility to try and befriend her and be nice to her falls to me, but I can't be bothered to spend the energy making all the effort anymore, and she kind of makes things feel awkward. I just want to enjoy time with my family.
Also she's obsessive about Instagram and TikTok. She has about 3k followers on Insta and 9k on TikTok and seems to want everything to fit that influencer lifestyle/aesthetic. She regularly pops out, or goes to another room for 30+mins at a time to post photos and videos online. Our parents have a nice house and I've discovered that when she goes to visit/stay there she makes a lot of content and passes it off as her house!
I feel bad, aibu? Any suggestions for improving the situation?
